NASA’s Curiosity rover captured this photo as it ascended the Martian mountain Mt. Sharp. A study proposes a new explanation for why Mars is a barren desert today, despite having

Schematic of the post-impact scenario for prebiotic atmospheres (Genda et al. 2017; Zahnle et al. 2020; Wogan et al. 2023). In this scenario, reducing power is delivered to the surface-atmosphere

On 15 October 1997, NASA’s Cassini orbiter embarked on an epic, seven-year voyage to the Saturnian system. Hitching a ride was ESA’s Huygens probe, destined for Saturn’s largest moon, Titan.

To understand where the measured flux from the planet is coming from we need to capture both reflected and thermal components of the light from the planet. This requires broad

Venus as seen by Himawari satellites. A photo with magnified sections to show just how small Venus is in the field of view of the observation satellites. Despite this limitation,
